In this work, the electrooxidation ability of nine pyridones was evaluated using cyclic
(CV) and square-wave voltammetry (SWV) in Britton–Robinson (BR) aqueous buffer solutions on a
glassy carbon electrode (GC). The dependence of electrochemical activity on pyridone structure was
elucidated by means of experimentally obtained spectra and quantum chemical calculations. Firstly, it
was shown that electrochemical activity is determined by the –OH group as a substituent in position
6 of the pyridone ring. By coupling the experimentally obtained UV-Vis spectra and DFT calculations,
the most stable forms, both protonated and deprotonated, were defined. The calculated values are
consistent with the electrochemical behavior observed, indicating that the deprotonated anionic form
was the most electrochemically active. Moreover, the impact of the substituent in position 3 of the
pyridone scaffold was discussed
